Re: Record and set changes

My recollection:

Restructure will only alter the contents of records; either data and/or
prefix portion. It will not adjust set order, only an UNLD/RLD (or
rebuild for an indexed set) will accomplish that.

If the set is not already in sort order, you MAY have issues with
updating the data once you define it as sorted. You're probably OK as
long as you don't do something that would cause IDMS to want to process
the set sequence (e.g., FIND/OBTAIN USING, STORE, MODIFY).

This last is where you're liable to run into issues. If you have
already defined the set as sorted, and then go in an MODIFY the sort
field contents, IDMS may ""notice"" the set is not correctly ordered, and
you MAY have a problem (This is pure guesswork; anybody else want to
chime in?).

Safest sequence is:

RSTU the new fields.
MODIFY to get all the right data established.
Define the set order as sorted.

As Bill points out, you can accomplish the final two steps together,
with an exit to the UNLD/RLD... but that isn't necessarily trivial.
